This is costing you margin and customers today

Three problems we see with prefab builders again and again.

Smart home is expected

Buyers compare. Without a professional KNX offering you lose premium customers to competitors, or deliver expensive, poorly planned workarounds.

Flat rates without a basis

Subcontractor packages are often 2–3× overpriced or under-specified. Without your own calculation the margin stays unclear, and the electrician invoices extra at the end.

Coordination overhead eats margin

Every gap between sales, planning and the electrician costs money. What the brochure says rarely matches the bill of quantities.

What venfree changes

Templates per house model

Configured once, exported hundreds of times. Separate profiles for every house type with matching devices and group address structure.

Sales specifies correctly

No KNX certificate needed. The planner guides room by room, the result is still ETS-compatible and ready for handover.

Transparent pricing

Manufacturer RRP live in the planner. No more guesswork, you know what KNX costs for this house before the contract is signed.

ETS handover without friction

Ready .knxproj file including group address structure. The electrician opens it in ETS and starts immediately, no back-and-forth, no rework.

What a partnership means

We work long-term, not transactionally.

Volume conditions

As a volume builder we negotiate framework agreements with manufacturers. Your customers benefit from better prices than the standard RRP.

White-label available

venfree as silent infrastructure behind your branded planning tool, no venfree logo, no venfree branding. Your house, your brand.

Test project free of charge

We configure one of your house models completely, bill of materials, ETS export, pricing calculation. Free and with no strings attached.


Too thin: extra costs from the electrician. Too fat: sales loses the customer. Without your own planning baseline both stay in the dark. venfree shines a light.
